Agentic commerce payments on rails that already authorize and settle

Who it's for

• Software teams adding an assistant

  You are putting an agent in front of a checkout, a booking or a renewal, and it needs to take the payment without a second system holding the card.

• Merchants asked about AI checkout

  Customers or partners are asking whether an agent can buy from you. This is the honest answer about what works today and what does not.

• Platforms with their own agents

  You already call the RapidCents API. The MCP server is the same surface, described so a model can use it without you writing an adapter per assistant.

Core capabilities

• RapidCents MCP Server

  An agent that speaks the Model Context Protocol reaches the same payment operations a developer would call directly, without a bespoke adapter per assistant.

• The same payments API

  Agents do not get a side door. They use the REST API that terminals, checkout and your own software use, so there is one set of behaviours to reason about and one place a payment can come from.

• Signed webhooks

  Outcomes arrive as signed events rather than something an agent has to poll for or assert. The signature is what lets your system trust that the result came from RapidCents and not from the agent.

• Tokenized credentials

  Card data is replaced by a token held in the RapidCents vault. A token is the control surface: it can be constrained, and it can be revoked without touching the underlying card.

• Idempotent requests

  An agent that retries — because a model timed out, or a step ran twice — must not create a second charge. Idempotency keys make a repeated request return the original result instead of a duplicate payment.

• A sandbox with documented test cards

  Agent behaviour is worth rehearsing before it touches real money, including the declines and timeouts, because those are the paths an autonomous caller reaches most often.

• One settlement trail

  An agent-initiated payment appears in the merchant dashboard beside terminal and online sales, refunds the same way, and reconciles into the same deposit.

How it works

Integrations

• Merchant dashboard

  Every transaction, deposit and exception lands in one dashboard.

• APIs and webhooks

  Connect the product to your own software with REST APIs and signed webhooks.

• Partner connectors

  Certified connectors for common POS, ERP and commerce platforms.

Security

• PCI DSS Level 1

  Processing runs on PCI DSS Level 1 audited infrastructure.

• Tokenization

  Card data is replaced with tokens, keeping raw credentials out of your systems.

• Role-based access

  Permissions and audit trails control who can see and do what.

Implementation

• Discovery

  A payment specialist reviews how your business gets paid today.

• Configuration

  Accounts, users and settings are prepared before you go live.

• Testing

  Run test transactions and confirm reporting before cutover.

• Launch and support

  Go live with training materials and post-launch support.

Pricing

• Transparent pricing

  Pricing depends on volume, card mix and configuration. Fee Check compares your current statement before you commit to anything.

For businesses in the USA

A direct answer for a business in the USA: the workflow, the limit, and what to confirm next.

• The payment workflow

  A practical view covers narrow US scenario where an assistant prepares a purchase and a customer grants the required payment authority. Name the agent, application, RapidCents interface and trusted result. Label production features, pilots and conceptual demonstrations clearly; protocol support alone does not establish complete autonomous purchasing. Confirm eligibility, presentment currency, settlement currency and the enabled payment methods on the USA merchant account before quoting them. An illustrative amount is an example, not a fee or a funding promise. Agentic Commerce does not, by itself, prove delivery or win a dispute.

• The problem and the limit

  The workflow should require documented spending authority, scoped credentials, idempotency and independently verified outcomes wherever implemented. Show timeout, repeated-request and changed-amount tests, plus revocation and human escalation. In practice, that the agent does not approve its own charge and that the integrating application has control responsibilities. Confirm eligibility, presentment currency, settlement currency and the enabled payment methods on the USA merchant account before quoting them. An illustrative amount is an example, not a fee or a funding promise. Agentic Commerce does not, by itself, prove delivery or win a dispute.

• What to confirm

  Before you rely on this, confirm US production availability of the actual MCP/API surface, supported methods/currencies and account prerequisites. Name responsibilities for customer consent and payment actions. Avoid universal assistant compatibility, worldwide merchant eligibility or an implied bypass of underwriting and authentication requirements. Confirm eligibility, presentment currency, settlement currency and the enabled payment methods on the USA merchant account before quoting them. An illustrative amount is an example, not a fee or a funding promise. Agentic Commerce does not, by itself, prove delivery or win a dispute.
